CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority under 35 U.S.C. 119 (f)to the application for Canadian Plant Breeders Rights which was filedfor the instant plant variety on Apr. 10, 2019, Application number19-9748.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Dahlia,botanically known as Dahlia sp., and hereinafter referred to by thevariety name ‘KLEDH18110’. ‘KLEDH18110’ originated from anopen-pollination in September 2014 in Stuttgart, Germany between theproprietary female Dahlia variety ‘DH-2014-1084’ (unpatented) and anunknown male Dahlia variety.

The seeds from the open-pollination were sown and plants were grown in agreenhouse for evaluation, where an individual plant designated‘KLEDH18110’ was selected from the group in May 2015 in Stuttgart,Germany. In May 2015, ‘KLEDH18110’ was first vegetatively propagated bycuttings. ‘KLEDH18110’ was found to reproduce true to type in successivegenerations of asexual propagation via terminal cuttings in Stuttgart,Germany, Tenerife, and Kenya.

SUMMARY

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Stuttgart, Germany.

-   -   1. Red flowers with a yellow center;    -   2. Dark green foliage; and    -   3. A compact, semi-upright growth habit.

DESCRIPTION OF THE PHOTOGRAPH

This new Dahlia plant is illustrated by the accompanying photograph of aplant approximately 5 months old and grown outdoors in Stuttgart,Germany. The photograph was taken in August 2017 and shows the flowersand foliage. The colors shown are as true as can be reasonably obtainedby conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctivecharacteristics of ‘KLEDH18110’. The data which define thesecharacteristics were collected from asexual reproductions carried out inLatina, Italy. Data was collected in May 2019 on 15 week-old plantspotted in week 5 and grown in a glass greenhouse. Color references areto The R.H.S. Colour Chart of The Royal Horticultural Society of London(R.H.S.), 5^(th) edition (2007).

COMPARISON WITH PARENTAL LINE AND KNOWN VARIETY

‘KLEDH18110’ is a distinct variety of Dahlia and is distinguished fromits female parent as follows. Whereas ‘KLEDH18110’ has red flowers andgood branching, female parental line ‘DH-2014-1084’ has orange flowersand medium branching.

‘KLEDH18110’ is a distinct variety of Dahlia and is most similar to thecommercial Dahlia variety ‘Dalaya Amba’ (also known as ‘KLEDH18010’).Differences between the varieties are as follows. Whereas ‘KLEDH18110’has red flowers with a yellow center, ‘Dalaya Amba’ has red flowers witha black center. Additionally, ‘Dalaya Amba’ flowers later than‘KLEDH18110’.

We claim:
 1. A new and distinct variety of Dahlia plant designated‘KLEDH18110’ as illustrated and described herein.
